-less-than (on-the-fly)

Not wanting to rain on your parade, but our \on-the-fly conditions are  
becoming ridiculous (and/or have been so for a long time already).

I think I'd rather have something like
\on-the-fly #(fly: (> page:page-number 5)) ...
or some similar syntax: a macro that just replaces the respective  
identifiers with the expression fetching them.

If we take a list at the currently existing conditions, it's pretty obvious  
that this is a rather open set.  So it might make sense just putting in  
some reasonably simple syntax calling Scheme, and stop extending the set  
with ever more special-cased not-quite-versatile variants.

A rather clean and easily implementable way would be to use something like
\on-the-fly #(fly-let ((n page:page-number)) (> n 7))
but I think we should aim for something that is as easy to write as  
possible.

The second has the advantage that it's straightforward to implement.  Any  
other nice proposals?
